AOI inspection principle introduced

1. CHS System Principle Description: Extraction of the pad Extraction of the flat part: red only Reflected extraction of a slow slope Extraction of a green: only a reflection of a glare Sharp extraction of a slope Surface: only the blue light that is reflected

2.Environment setting screen limit setting: there are setting user interface setting and withdrawing confirmation user limit setting password setting: administrator, tester, programmer, hardware maintenance and repair personnel machine authority setting new machine time setting Set: the new machine general Japanese time, should be changed to local standard time Language setting: the default support for three languages: F10-Japanese F11-English F12-Chinese which also has Korean internal, but need to enter the settings to replace the top three one of

3. File Network Settings Archive Address Component Library: Local and Network Checking Procedures: Local NET: Network Note: Note the difference with CTS settings backup

Second: basic programming model

1. New inspection program: New program name Longitudinal longitudinal input of the circuit board (need to use the ruler to measure first) The track width is 0.5mm larger than the actual amount of clamping The general situation set 0.5mm The default “left”, as the case may be Reference position Photographic size components The name of the library that is the magnification of the photographic resolution 10um The smaller the value the higher the resolution, the larger the picture looks out 1280 * 1024 can use the existing, can also be new Note: Under normal circumstances photographic magnification, camera size and components Three of the same name of the library

2. Simple outline of the component box Automatic extraction box is mainly used for PCB board over the local deformation of the furnace is the location of the component location, the size of the board bend may be the subject of the same theme box and component size pad frame contains positioning frame and test box Generally placed in the middle of the components, not too much, the electrode patch components do not frame part of the electrode Note: The first use of MARK PCB positioning board, the first component selected after the first automatic positioning with a frame positioning component and then testing

3. Automatic extraction of the box has a default level of 15% General If the test shows the main component and the pad error, see if it needs to be debugged Extraction out of the way pad extraction and component extraction pad that is positioning the first pad, find the pad And then the other components to a fixed frame position Note: If you see the pad, box all the pads, if you can not see, be sure to estimate the cover is about the pad, or follow-up pad test parameters will be wrong components drawn components Body extraction and electrode extraction Note: If you use the component electrode extraction, be sure to “above the electrode” selected

4. The lack of solder plate box set the central part of the red solder less the better The main part of the red solder around the blue part of the less the better The main focus of the blue center of the pad electrode and the level of electrode components center distance, The bigger the value the better Note: For some diode gallbladder capacitors and other electrodeless components, do paddle frame should pay attention to the size of the pad to be covered Otherwise it will be “abnormal solder invasion” Alarm bad Pad longitudinal offset General settings 60 % Of the vertical offset of the pad 60% of the general set of welding forming angle This parameter is mainly to detect less tin color parameters set blue blue is greater than a certain percentage to PASS pad invasion of solder in the overall color parameters set only the brightness of red and green Blue tricolor solder central part of the color parameters in the red red less than a certain percentage to PASS

5. The area of ​​the mounting frame is mainly drawn out of the test frame color Note that the use of “binary” circuit board area set opposite the area of ​​the device The end of the area is limited to the test ring inside the color angle of the limit will be a little strict

6. IC editing is the default two IC box block body and IC automatically draw the box pin spacing (mm) pin spacing can be used “window information” “size” which gradually step up after the measurement pin number direction default is Counterclockwise setting Note: To set the first frame of the pin counterclockwise to the starting position, such as setting the back position, automatically copy the other pin will be wrong Pin generally not numbered If the request number, you can better Specific pin problems for easy statistics, but this method is more time-consuming Pin number Increment if set to 0 will follow the 1 2 3 4 Increment If set to 1 will follow 1 3 4 5 Incremental Other data changes in sequence Check pin The number of ICs set counterclockwise first pin after the need to copy the number of pins Note: This data is for the IC automatically withdrawn frame positioning is not allowed, if appropriate to enlarge the extraction frame, it is necessary to set the number of specific pins, or IC pin automatic copy may be based on the pin spacing and extension of the box more than the test standard short-circuit that is set to bridge the longitudinal position of the root drawn out into the root of the pin out and pin edge Draw the rough root of the root pumping thick The first line from the root of the line to find the root of the pinch, red above 50% and the emergence of 4-6 consecutive pixels Line out of the edge of the pin If the root and the middle of the same color, the need to use the edge Draw out the note: the edge of the pin out of the set only grasps the brightness At this point the pin should be automatically drawn thick frame to the component body frame a little, so as to find the pumping horizontal position of the drawer horizontal position There are three ways to pull out the general default Way “pin out that is, if the front-end of the pin frame is not in place, the definition will automatically find the most front-end pad out that the positioning pad algorithm: out of the box automatically draw out the outermost box in the red” binary “display White is drawn OK Longitudinal Offset Pixel 3 and less than 3 pixels in front of the pad Laterally offset Pixel 3 and up to less than 3 pixels from the pad Error Solder Bridge Exceptional Pixel 7 is pulled from pin 7 pixels outside the root of the unexpected part of the short-circuit area width of 20% smaller the narrower welding angle of the inspection area of ​​the front-end pin and the solder length of the pin too front pad Small side end is welded solder wetting angle of the main tip portion for extracting blue pin narrow width pad IC IC pin + pin distal portion extracting luminance + the luminance of blue

Three: CAD processing and import

1. Excel document finishing XY angle position material number five data, note the following points: Can not have special characters such as # * Number inside the column should be a number of packages Best to remove the save CSV (comma separated) mode to save the standard Of the two columns, can not appear in two or more and merge into the same column five data sequence is not particularly limited

2. Multiform Conversion Tool Software Input file Five Collated Data csv Document Location Note: This file is a file type ending in .csv. Output file Using the Multiform software to arrange the OK. File location that can be used directly by Omron AOI Note: This file Is the .cad file type offline programming placement address: c: program file OMRON CTS cadfile *. Cad online test placement address: c: program file OMRON VT- RNS cadfile *. * .csv and * .cad names to be consistent, the general name of the machine type PCB name (16 charctor) PCB board name PCB size (mm) X horizontal size Y vertical size Alignment (mm) General default, do not arbitrarily debug Divides by field Comma commas must be hidden in the Excel column between hidden Comma-separated Tab text 8 spaces to the default value do not hook Divides by fixed in accordance with the fixed length of this item generally do not use X coordinates X Axis matching column Revised value 1 X compensation value of the general election Mul Mul Y coordinates coordinates of the direction of the axis Revi sed value 1 Y compensation value is generally selected Mul multiplied Note: XY axis of the various test points should be placed in the same quadrant, if not, you can use the overall offset change the center point plus or minus, the use of Excel for the entire column Add or subtract, replace the original column Mount angle Angle matching column Revised value 1 Angle compensation value General Add Add Add Note: the angle data must be positive, can not appear “-” The negative sign Componet name Position matching column Componet No. Pieces matching column Edder skip The following data from the first few lines up, and sometimes there will be the first line is the subject, you need to set “1″ to skip the first line, the general order OK here Is zero, you can not set the Conversion Conversion Set the OK after the above CSV to convert the CAD file “OK”

3. TIMap CAD file inspection software is to check the CAD file has been converted to the location of the direction of the size of the angle is correct PCB name PCB size PCB size PCB size Note: If the position is not correct, you can Multiform Conversion Tool Software Standerd Position Longitudinal position Front Front Rear Latch direction Horizontal direction Left Left Right Right After importing the TIMAP software in the above direction, check the Timap software for viewing in the above direction. Note: If the direction is not correct, the columns matching the Mount angle in the Multiform Conversion Tool software are correct. Select Add Add to compensate for the correct point before importing TIMap software view

4. CAD document import test program import sequence: select CAD mode → open CAD file → product number correspondence table selection → all position adjustment → align the center position → adjust the position (1000 times 100 times 10 times 1 times) → have not changed Add to the blue black line component → Paste all → Move the single component test location is correct → PCB copy → MARK settings → Save product number correspondence table selection If there is no previous product number correspondence table or need to be added should be added Associate the CAD file with the already edited component in the component library New: Add to group → Copy → Copy the newly created component Default to the append group → Click the product number to log in → Then the component type and CAD The item number Or position → The new component association will turn blue Note 1: The components in the species of the same, you can directly select the component species, and then click the product number to log in, you can add OK but after adding Check for correct orientation, incorrect orientation, swivel change (there is a “CAD component image on the left below “) In the components of the species is not the same, you can find a similar, according to the component editing method, copy the new name, set the color OK, select the need to associate the components in the association, according to the above” New ” Method Connection 2: Capacitor General If the package electrode and the body color are the same, multiple item numbers can be associated with the same component type. Note 3: In general, the resistor is marked with the package name and MARK identifier. After the convenience of the association Note 4: Before all the paste to check whether the entire circuit board before the addition of components or copy of the components of the species box, if any, must be deleted, or all will appear after the duplication of the component box , Wasting test time and disrupting test program Note 5: A “datum rotation” appears after the “product number login” At this point, the direction of the “camera image” and the large image are large, and is the “CAD component image” orientation below Consistent, Inconsistent changes Note 6: After all the paste check “move a single component test location is accurate Indeed “, only a single debug, can not be in the” board – circuit board “→ circuit board inside the debug, which is the overall adjustment

5. Multi-board copy If it is two puzzle board directly in the “board – circuit board” → “copy” option can be multi-board, such as horizontal and vertical three vertical “board – circuit board” → ” Copy “→ in the pop-up box must be transferred to the horizontal point three arrow down two arrows in the vertical direction, and then to determine the electrode, or in the same location will be copied six test box, remember here

6. MARK SETTING Before MARK setting, be sure to go to “SINGLE BOARD – BOARD” → “SINGLE BOARD” → “SINGLE BUFFER” → CORRECT REFERENCE POSITION → “MARKING CENTER” → FIRST BY B → appearance → pumping color parameters → general MARK is red, red pumping thick Note: Each MARK point must be done before re-election “calibration reference position” → “mark center” Note: If MARK element test in the “election Model Comparison “→” Failed to acquire the reference position “, and check whether the” Check Reference “→” Correction Mark “→” Outline “parameters are selected
